District Court Finds IRS Standards for § 501(c)(4) Status Unconstitutionally Vague

In a significant ruling for nonprofit advocacy organizations, the U.S. District Court for the District of Columbia has held that the standards applied by the Internal Revenue Service to determine eligibility for § 501(c)(4) tax-exempt status are unconstitutionally vague. In Freedom Path, Inc. v. Internal Revenue Service, et al., (USDC DC Case No. 20-cv-1349 (JMC)), the court granted partial summary judgment to the plaintiff, finding that both the Treasury Regulation and the IRS Revenue Ruling used to deny its application transgress the heightened vagueness standard applicable to civil regulations affecting First Amendment speech. However, the court stopped short of granting Freedom Path § 501(c)(4) status, finding that neither party had proposed a constitutionally permissible alternative standard grounded in the existing statutory and regulatory framework.

IRS Reverses Course on Corporate Reorganization Guidance: Withdrawal of Proposed Regulations and Reinstatement of Prior Ruling Procedures

On September 30, 2025, the Treasury Department and the Internal Revenue Service (IRS) took a significant step by withdrawing two comprehensive sets of proposed regulations issued earlier in the year that would have substantially altered the landscape for corporate separations, incorporations, and reorganizations.
